Water quality. Guidance on the use of in vivo absorption techniques for the estimation of chlorophyll-a concentration in marine and fresh water samples Ingestion-build-209208 Why should you use BS1 Scope This European Standard provides guidance in the use of in vivo absorption techniques to quantify chlorophyll a concentration in marine and fresh waters. This European Standard is comprised of the following: definition of the equipment requirement; a priori data and mathematical tools; recommendations for verification of measurement system performance and consideration of factors that can influence measurements; listing of the procedures to be
